– The Riser Protection Net (RPN) replacement has enabled Equinor to continue its Heidrun operations without costly disruptions, Ståle Karlsen, Project Manager at OceanTech, said.

In 2019, Equinor hired OceanTech to replace riser protection net fairleads at the Snorre A platform in the North Sea. The project has enabled Equinor to continue production without costly disruptions.

As more and more platforms on the Norwegian continental shelf are reaching their design life, installation components are starting to show wear and tear caused by the ravages of time existing in a harsh offshore environment. An example of this is damages caused by corrosion. Salt, water, air, and rough mechanical impact on metal are all ingredients in a corrosive meal.

Successful riser guard replacements require careful planning and a customised methodology for cutting, rigging, and lifting that addresses the project’s unique nature.

An OceanTech engineering team developed rigging and lifting methods for a successful installation of 725 sacrificial anodes across 67 assets at the Dudgeon Offshore Wind Farm. This helps prevent internal galvanic corrosion inside transition pieces, saving Equinor time and money in asset maintenance.
